Yeah, GNU/FSF have never put any resources in to GNU social apart from maintaining the general !fs politics worldwide.
Originally Evan had startup grants, I just put in my free time (which I barely have any left nowadays) and @diogo got the gsoc stuff.
While I enjoy the !ostatus solution much more than ActivityPub maybr we should see what has been generated "outside" of !gnusocial .) Think of how many people have managed to find their way out on the !fediverse even if it's maybe not via GS specifically. But it's all AGPL .)
